What is a potential limitation of post-processing in DR for high-contrast detail perception?

• A. Over-Processing Can Create Artificial Edges
• B. Post-Processing Always Improves Visibility
• C. It Reduces Noise
• D. It Cannot Affect Subtle Features

Answer: (A)

Post-processing can improve how the image is displayed, but pushing it too far in high-contrast regions can create artificial edges. When sharpening, high-pass filtering, or edge enhancement is applied aggressively, the bright-to-dark transitions may be exaggerated, producing boundaries that don’t exist in the actual anatomy. These artificial edges can mislead interpretation, changing the apparent size, shape, or location of structures and potentially masking subtle, diagnostic features. While post-processing can help in some cases, it isn’t guaranteed to improve visibility and can introduce artifacts or distort nearby details.
